145 nasolacrimal obstruction patients (150 eyes) were treated with the modified dacryocystorhinostomy operation (using periostium). Group I: 45 cases with torn nasal-membrane. Group II: 145 cases with intact nasal-membrane. The general results are the same in both groups but the functional result of group II is much higher than that of group I. Thank to using periostium in operation, the treatment result is much increased. Six months after operation, the treatment result is stable. The technique is quite simple

PURPOSE: The correspondence between the canaliculus irrigation test, dacryocystography, and Jones test in patients with epiphora was investigated. METHODS: The study included 494 eyes of 359 patients who complained of epiphora and underwent both canaliculus irrigation test and dacryocystography from May 2001 to March 2006. Sixty-eight eyes from 34 patients diagnosed with functional lacrimal duct obstruction took Jones tests. Factors such as age, sex, duration of epiphora, and site of obstruction were analyzed in terms of correspondence of the tests. RESULTS: Between the canaliculus irrigation test and dacryocystography, correspondent rate was 55%. Correspondence had no relation to patient age, sex, duration of epiphora, or site of obstruction. Between Jones test and dacryocystography, the correspondent rate was 47%. Factors affecting the correspondences were not significantly found. CONCLUSIONS: A canaliculus irrigation test can give useful information with high correspondence rate of dacryocystography in the case of 'not pass' or 'pass without regurgitation'. Therefore dacryocystography should be utilized in "pass with regurgitation" cases by canaliculus irrigation test.

A dacryocele is an uncommon complication of obstruction in nasolacrimal drainage system. It seems to occur as a result of a distal obstruction at the Hasner's valve and an proximal obstruction at the Rosenmuller's valve and has mostly been treated by opthalmologists until now. We present a rare case of dacryocele with recurrent dacryocystitis, which recurred after lacrimal probing and bougination. Dacryocele has been treated successfully through marsupialization under the endoscopic visualization.

In this prospective randomized controlled study, a total of 70 patients (76 eyes) diagnosed with acquired nasolacrimal duct obstruction operated by DCR with intraoperative mitomycin C 0.4mg/ml appication to the osteotomy site for 3 minutes. The results of the DRC surgeries were evaluated by objective findings such as irrigation, height of tear meniscuc, ostium size and subjective symptoms. Among the 76 eyes, 96% of patiets remained total symptoms free after 6 months of follow up. Mean ostium size 2.861 (0,785mm. There were no complications such as abnormal nasal bleeding, mucosal necrosis or infection

The study was done on 9 children aged from 4-16 with 10 eyes having congenital or traumatic naso-lacrymal duct obstruction. These eyes with associated canalicular stenosis or obstruction were treated by dacryorhinostomy (DCR) and silicone intubation in six months. The successful prevalence of DCR is as high as that of DCR on adult: 90%. Among them, 70% were functional success. One eye having recurrent obstruction is traumatic case. The failure occurred when silicone tube is still inside the canacular. DCR in children is not difficult than that in adult. The complication is rare and easy solved.

A dacryolith is a concretion within the lacrimal drainage system. Although it may cause intermittent epiphora without inflammation, dacryoliths are often underlying contributors to recurrent or chronic dacryocystitis. It may occur anywhere along the lacrimal drainage system, albeit most commonly in the lacrimal sac. We report an interesting case of a dacryolith presenting as a mass of inferior meatus, which was managed via endonasal endoscopic approach.

Epiphora is one of the most common problems in ophthalmological practice, and is caused by dysfunction of the lacrimal pathway. The lacrimal drainage system is a continuous anatomical structure consisting of the lacrimal punctum, inferior and superior canaliculi, common canaliculus, lacrimal sac, and nasolacrimal duct. Lacrimal disease can be medically treated in case of acute inflammation or partial obstruction at the beginning of treatment, but surgical treatment is necessary in most cases. This paper discusses the etiology, clinical features, diagnosis, and surgical treatment of various lacrimal diseases through a selective review of the relevant literature. Advances in lacrimal duct surgery can now be performed in such a way that the structural integrity and normal physiological function of the entire efferent lacrimal pathway is preserved.

OBJECTIVES: Many factors influence the outcome of endoscopic dacryocystorhinostomy (DCR). One of the most important prognostic factors is the level of obstruction in the lacrimal drainage system. The main objective of this report is to evaluate both the frequency of obstruction by anatomical region of the lacrimal drainage system on dacryocystography (DCG) and the surgical outcome of endoscopic DCR according to the obstruction level. METHODS: A retrospective series of 48 patients (60 eyes) who had undergone endoscopic DCR from January 2005 to November 2007 were enrolled. Preoperative evaluation consisted of a standard examination which included lacrimal irrigation, probing, DCG and osteomeatal unit (OMU) computed tomography. Patients were classified into four groups according to the obstruction level on DCG. Surgical outcome was evaluated postoperatively by subjective improvement of epiphora and patent rhinostomy opening on nasal endoscopic exam. RESULTS: Of 60 eyes, the levels of obstruction were the common canaliculus in 14 eyes (23.3%), the lacrimal sac in 13 eyes (21.7%), the duct-sac junction in 13 eyes (21.7%) and the nasolacrimal duct (NLD) in 20 eyes (33.3%). The ductsac junction obstruction was treated most successfully (100%), followed by NLD obstruction (90%), common canaliculus obstruction (78.6%) and saccal obstruction (69.2%). CONCLUSION: In patients with lacrimal drainage system obstruction, preoperative evaluation of obstruction level using DCG may be helpful for predicting the surgical outcome of endoscopic DCR. The saccal obstruction may have a worse prognosis than the other obstruction levels.

The diagnosis and treatment of the lacrimal passage obstruction with lacrimal endoscope was investigated and its subsidiary surgical procedures were evaluated. Ninety-three patients (109 eyes) with lacrimal passage obstruction, including presaccal canalicular obstruction (PSCO) and nasolacrimal duct obstruction (NLDO), were examined under a lacrimal endoscope, and the obstructions were treated with laser or micro-drill. All patients were followed up after the operation for 3-6 months. The difference between the laser and the micro-drill treatment was observed. During the period of follow-up, the curative rate was 82.57%. The healing rate in PSCO group and NLDO was 80.36% and 84.91% respectively (P>0.05). After treatment with the laser, the healing rate was 93.33% in the PSCO group and 66.67% in the NLDO group respectively (P<0.05). After treatment with the micro-drill, the healing rate in PSCO and NLDO groups was 65.39% and 94.28% respectively (P<0.01). The lacrimal passage obstruction can be observed and treated directly through the lacrimal endoscope. Choosing different surgical procedures in operation according to the locations of the obstruction is helpful to improve the effectiveness.
